1. FLORISTIC COMPOSITION AND DIVERSITY IN TERRA FIRME FOREST UNDER WATER STRESS IN THE AMAZON
ABSTRACT The studies on floristic composition are an aid in the understanding of the structure and dynamics of the plant communities, fundamental parameters for its management and conservation. Thus, the objective of this work was to evaluate the floristic composition, species richness, Shannon’s diversity and models of species abundance over a 10-year per

3. Environmental factors affect population structure of tree ferns in the Brazilian subtropical Atlantic Forest
ABSTRACT Tree ferns are important elements of tropical forests, mainly because they are common and provide microhabitats for epiphytic plants. Due to their ecological importance, the aim of this study was to evaluate population structure, distribution, and influence of environmental variables on tree ferns in the state of Santa Catarina, southern Brazil. All

5. Antibacterial Activity of Polygonum Orientale Extracts Against Clavibacter Michiganensis subsp. michiganensis, the Agent of Bacterial Canker of Tomato Disease
Abstract Clavibacter michiganensis subsp. michiganensis (Cmm), which is a Gram positive bacterium, causes the bacterial canker of tomato disease. The purpose of the study was to evaluate the antibacterial activity of Polygonum orientale extracts against Cmm. In this study, firstly, effects of three extracting parameters (extractive time, extractive temperat

6. Gene pool sharing and genetic bottleneck effects in subpopulations of Eschweilera ovata (Cambess.) Mart. ex Miers (Lecythidaceae) in the Atlantic Forest of southern Bahia, Brazil
Abstract Forest loss and fragmentation are the main threats to the maintenance of the Atlantic Forest, an important global biodiversity hotspot. Because of the current critical level of deforestation, ecological corridors are needed to facilitate species dispersion and gene flow among fragments. This study was conducted to investigate the genetic variability

8. Thermal requirements and age-specific life tables of cowpea aphids in cowpea under natural field conditions
RESUMO: As exigências térmicas dos insetos, bem como as tabelas de vida, são ferramentas importantes para o manejo ecológico de pragas. Assim, objetivou-se elaborar as tabelas de expectativa de vida específicas para Aphis craccivora em diferentes épocas do ano e, como base em suas exigências térmicas, prever a ocorrência de adultos em condições de

10. CHANGES IN THE SOIL STRUCTURE AND ORGANIC MATTER DYNAMICS UNDER DIFFERENT PLANT COVERS
ABSTRACT The soil properties reported in areas with different management provide useful information about the systems’ operation, state of conservation and resilience. In this way, this study evaluated physical properties and organic matter dynamics of soil under different plant covers in seven areas consisting of: five areas under ecological restoration (

11. Temporal variation of bacterial population and response to physical and chemical parameters along a petrochemical industry wastewater treatment plant
Abstract: The petrochemical industry has played a considerable role in generation and release of waste in the environment. Activated sludge and facultative lagoons are commonly used for domestic and industrial wastewater treatment due to their low-cost and minimal need for operational requirements. Microorganisms present in wastewater treatment plant (WWTP)

12. Multiple nesting attempts and long breeding seasons of Mimus gilvus (Aves: Mimidae) in southeastern Brazil
ABSTRACT This study describes aspects of the life history of the Tropical Mockingbird Mimus gilvus (Vieillot, 1808), including the breeding period, clutch size, nestlings and a list of plants used for nesting. Nests were monitored in an area of Restinga (sand-coastal plain) habitat in a protected area in southeastern Brazil. The data from 181 nests during fi
